Safety Definitions and Precautions
Safety Definitions
These safety terms identify information you must read prior to installing or operating the humidifier.
CAUTION: Indicates a hazardous situation which, if not avoided, could cause bodily injury
or property damage.
WARNING: Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
Safety Precautions
Make sure you read and understand the following safety hazards before installing, using, or working with the
humidifier:
CAUTION: Voltage Hazard.
Can cause electrical shock or equipment damage.
Disconnect HVAC equipment and any electrical outlet being used for the humidifier installation.
WARNING: Electrocution and Water Hazard.
Can cause death, blindness, and water damage to the home and HVAC Equipment.
CAUTION: Condensation, Fire, and Freezing Water Hazard.
Can cause failure of fan or limit control or result in water damage to home.

GETTING
STARTED
The installer should review these points with the homeowner and answer any questions they have before
leaving the job site.
• Achieving Humidity Setpoint. It may take up to a week of continuous operation to achieve the humidity
setpoint, especially if the home is dry when the humidifier is installed. This also depends on such factors
as weather, size of home, furnishings in the home, and insulation.
• Ideal Humidity. Home building industry experts cite 35% relative humidity as ideal for comfort and
safeguarding the home during the typical dry season. Homeowners can adjust to their own comfort or
until there is condensation on the windows. Lower the setpoint if condensation appears.
• Unit Not Humidifying. If the humidifier is not running but the humidity is below the setpoint, the
humidity control may have a frost protection setting to prevent window condensation from appearing.
• Home Ventilation. Excessive ventilation sends moist air outside and replaces it with dry air. This can
make it hard to maintain the humidity setpoint. If installing a ventilator, use a solution that retains
moisture. An Energy Recovery Ventilator (ERV) is recommended.
• Cleaning Requirements. The humidifier pad should be changed at least once a year. The water trays of
the humidifier should be cleaned at that time. See Operation and Service section for details.
• Energy Consumption. It is important to explain that with any humidification solution there is a cost
associated with converting water to humidity. The humidifier utilizes the air heat and air flow in your
ducting to make this conversion, which has gas and/or electric costs that depend on your HVAC system
type and setup.

GETTING
STARTED
Personal Safety
• Wear safety glasses while installing the humidifier.
• Do not cut into any air conditioning or electrical line.
• Follow professional safety standards and all local regulations for plumbing, electrical, and mechanical
considerations.
Mounting Location
• Mount the humidifier in a level position to avoid water damage and ensure maximum output.
• Location must have access to a water line, drain, and power.
• Do not install the humidifier where the ambient temperature is lower than 34°F (1.1°C) or higher than
90°F (40°C).
• Mounting area must be strong enough to support humidifier weight (up to 10 lbs).
• Do not mount directly to ductboard.
• If used near a pool or spa, make sure the humidifier can not fall into the water or be splashed.
• Ensure that the top and bottom covers of the humidifier can be removed and that the pad is accessible
from the chosen location.
Water Supply and Drainage
• Consult local plumbing codes for drain size, material, and maximum temperature allowed.
If Replacing an Old Bypass Humidifier
The humidifier is not identical in size and shape to other bypass humidifiers. Before performing a retrofit
installation, you might need to:
• Dry-fit the humidifier to the existing ducting, plumbing, and wiring before fastening it to the duct to ensure
that the existing connections will reach the humidifier.
• If the duct opening of the old humidifier is not the right size for the humidifier, choose a new location or
cover the old opening with a piece of sheet metal and cut a new opening specifically for the humidifier
using the template provided.
Important Installation Requirements
Failure to comply with these requirements will result in voided warranty, improper installation,
and service callbacks.

MOUNTING
Choosing a Mounting Method
Before beginning Mounting:
I have confirmed local codes for proper plumbing practices.
I have chosen an installation location that meets the requirements on page 4.
Bypass humidifiers use the pressure difference between the supply
and return to move duct air through the humidifier. Access to both
the supply and return are required. The bypass humidifier can be
positioned on either the supply or return duct.
MCR29871
STEP ONE: Select the Mounting Location
Choose a location that has access to a water supply
pipe. Cold or hot water can be used.
Select a vertical or horizontal surface on the HVAC
duct work, with adequate space clearances, where
the humidifier can be mounted.
Ensure the location is near a drain. Consult local
plumbing codes for proper drainage. If no main
floor drain is available, see “Appendix B: Advanced
Draining.”
Location must also have access to 120 VAC power to
the included transformer.

STEP TWO: Install Mounting Template to the Duct
Position the template on the duct.
• Make sure the template is level and in the desired
position on the duct. Peel adhesive backing
and press template firmly into place in desired
mounting location.
Ensure proper clearances from the air-conditioning
coil inside the duct.
NOTE: The HE400 humidifier extends into the duct
1/2 inches.
• For best performance, maintain at least 24
inches downstream of open air space inside the
duct.
Cut the sheet metal, following the template outline.

STEP THREE: Configure Humidifier
Configure the humidifier bypass outlet to the side
that best fits the application.
If the bypass needs to be on the other side, remove
the top and bottom covers.
Pull the bypass clamps apart from center to remove
the bypass; snap it back into place with the outlet on
the desired side.

MOUNTING
Ensure that the pad is accessible. The handle of
the pad holder and side panel of the humidifier
can be switched so the pad holder can be removed
(opposite side of the bypass duct opening).
To remove the handle for the pad holder, slide it
toward the back of the humidifier, then pull it away
from the humidifier.
To remove the opposite side panel, place a
screwdriver into the two slots on the back of the
humidifier, and pop the panel off.
Snap the pad holder handle and side panel back into
place in the desired configuration.
STEP FOUR: Mounting
Secure the support hooks on Bypass models to the
bottom lip of the hole.
Push the top of the humidifier back against the duct.
Verify the humidifier is level and fasten the
humidifier to the duct using two self-drilling sheet
metal screws provided.

MOUNTING
Before proceeding to the next step:
I secured the humidifier to the duct as instructed.
Bypass mounting is complete. Go to page 12.

STEP FIVE: Bypass Duct Installation
On the duct opposite the humidifier Bypass install,
cut a 6-in. diameter duct hole.
• If the humidifier is on the supply duct, the 6-in.
diameter hole should be on the return.
• If the humidifier is on the return duct, the 6-in.
diameter hole should be on the supply.
Secure a 6-in. round duct starter collar into the 6-in.
duct hole.
Use rigid or aluminized flexible 6-in. duct to connect
the starter collar to the humidifier bypass port.
Secure the duct to the humidifier port with self-
drilling sheet metal screws using the pre-drilled
holes on the bypass port. For added seal, wrap sheet
metal tape around the duct to port connection point.
